We establish a decidability boundary of the model checking problem for infinite-state systems defined by Process Rewrite Systems (PRS) or weakly extended Process Rewrite Systems (w...
The Brane Calculus is a calculus intended to model the structure and the dynamics of biological membranes. In order to express properties of systems in this calculus, in previous ...
We solve the open problem of the decidability of Boolean BI logic (BBI), which can be considered as the core of separation and spatial logics. For this, we define a complete phas...
Metric Temporal Logic (MTL) is a real-time extension of Linear Temporal Logic that was proposed fifteen years ago and has since been extensively studied. Since the early 1990s, it ...
We consider positive rules in which the conclusion may contain existentially quantified variables, which makes reasoning tasks (such as Deduction) undecidable. These rules have t...
